Steve said: "if you do your front and rear bars a certain way, you'll have a neutral-handling car - i.e. one where the front and rear wheels let go at the same time. Most say an understeering car is safer for ordinary drivers."
Yes, and that was my point in saying why it is wise to think about only making a change in one end of the car.
Understeering may be preferable in that it in some ways limits the ability of a driver to get overextended, as the instinctive reflex of lifting off the throttle quickly increases front traction and tends to end the crisis, whereas in a car that is significantly tail-happy getting off the gas will likely bring on snap-oversteer and that car will go off the road tail first.
However driving a car with neutral steering or slight oversteer gives a driver--or in any case this one--the ability to explore the limits of traction and how to steer with the throttle as well as the wheel. This is fun on the street and mandatory on the track.
